TL;DR: In this paper, the dominant processes with a geometrically non-defined cutting edge are analyzed based on the position of hard finishing in the process chain of gear manufacturing, and the analyses of the processes include functionality, the development status, respectively, maturity as well as identifiable trends.

TL;DR: In this paper, the authors show that dry hobbing with PM-HSS is feasible and economic for 1.5mm to 4mm external gears, and a method to determine guide values for dry guiding is presented.

TL;DR: A three-year study by the CIRP's Collaborative Working Group on Surface Integrity and Functional Performance of Components as discussed by the authors reported recent progress in experimental and theoretical investigations on surface integrity in material removal processes.

TL;DR: In this paper, the authors reviewed the evolving and conventional conditioning technologies based on technical and commercial aspects and defined terms in the field of conditioning for abrasive layer, and put emphasis on the description and monitoring of the abrasive layers.

TL;DR: In this paper, the authors present a view from 23 machine tool builders based on a survey made in interviews and during the EMO and IMTS machine tool shows to understand what are the main research challenges in the extensive industrial use of the process.

TL;DR: In this paper, empirical, analytical, numerical as well as FEM-based methods describing the chip geometry and predicting the tool life and cutting forces have been developed to capture quantitatively the tool wear progress and the cutting loads.
